Company patents
FANUC CORPORATION
Fanuc Corporation's patent strategy is heavily concentrated in core manufacturing technologies, with Manipulators & Robotics (41.3% of portfolio) and Industrial Control Systems (33.4% of portfolio) dominating its portfolio. While Motor Control showed a significant 37.5% YoY growth in 2024, it's surprising to see a sharp decline in patenting across nearly all categories in 2025 and so far in 2026, with Plastics Shaping & Molding experiencing a complete cessation of patenting in 2026 (YoY -100.0%), indicating a potential shift away from this area.
